Std.NonEmpty.reduce

1 declaration

fn

reduce: &Std.NonEmpty.NonEmpty[T] -> fn(T, T) -> T -> T

This is a callable function.

What it does

The elements combined from the left, starting from the first one.

No initial value is asked for, because the first element is one. This is

the fold that cannot be given the wrong starting point.

Read the signature

  • The text after the name is the type checked by Pudu.
  • Read arrows from left to right: inputs come first, and the final type is returned.
  • & borrows a value for this call instead of moving or copying it.
  • Names inside [ ] are type arguments, such as the item type held by a collection.
